[llvm-commits] Bug in "call __chkstak" on 64 bit OS

[Anton Korobeynikov]

> The "__chkstk" function is in ntdll.dll. In my OS, the JIT is loaded to an address which is more than 2Gb away from the ntdll.dll, thus the call to this function fails. I will investigate other system calls as well. But regardless of other calls, this fix is needed.  The definition of W64ALLOCA (below) assumes that we use an i32 immediate, thus we can’t use it.
Surely the fix is needed. It just needs to be done in proper way.
